Q:
Why is the location of the orifice tube changed on some vehicles?
A: The orifice tube is
a fixed opening. When the A/C system shuts off, both sides of the system
will equalize through the orifice tube. When that happens, there is a definite
'hissing' sound. Because that sound can be heard inside the passenger compartment
of the vehicle, it was decided to move the orifice tube further up the liquid
line (on some vehicles) to reduce the noise. |
